Setup Checklist

FRONT PANEL CONTROLS AND DISPLAYS

Figure 1: Front Panel Connections of the SC-602 amplifier.

Following are brief descriptions of the controls described in Figure 1. More detail on these

controls can be found in the next section.

(1) Power Switch

This button forces your SC-602 amplifier into standby mode. The power LED turns amber,

the numeric LED shuts of

f, and the amplifier puts out no power. The unit will remain in this

mode until the POWER button is pr

essed again. To fully deactivate (i.e. power down) the unit,

use the main power switch on the back panel.

(2) Power LED

This LED illuminates when the power is on. Blue indicates normal operation. The LED turns

amber when the unit is in standby mode or the remote has been used to deactivate the unit,

and dims when the unit is in night mode.

(3) Mic Input

Connect the supplied microphone for the Auto-EQ feature to this mini-jack input.

(4) Remote Eye

This is the eye that receives infrared commands from the supplied remote control.

(5) Crossover

Use these UP and DOWN buttons to select the frequency below which all signals will be

outed to the subwoofer (for example, 80 Hz), rather than to the main speakers. The

frequency is briefly indicated on the LED display, then the display reverts to showing the

subwoofer’

s volume level. The slope is fixed at 24 dB/octave. T

o deactivate the crossover,

press BOTH the UP and DOWN crossover buttons at the same time - two dashes on the

display indicate the crossover is deactivated and the woofer plays all frequencies presented

to it. Please see page 8 for a more detailed discussion on crossovers.

6) LED Numeric Indicator

This LED supplies information on volume, crossover, woofer type, and other information. The

“

light” button on the remote deactivates this display. Upon startup, the display shows the

model of subwoofer the SC-602 amp is set to, then reverts to the volume indicator.

(7) Volume Control

These buttons allow you to balance the output from the subwoofer with the output of the

main speakers in your system. The volume should be set to achieve similar volume level of

both the main speakers and subwoofer. The default volume is 30.

Note: Volume can also be controlled by using the supplied remote.

WARNING: Some manufacturers preset their receivers with the Sub-Out (a.k.a. LFE)

channel signal at a minimum level. It is very important to verify that your receiver Sub-Out

channel is set to the same output level as your front right and left channels. Refer to your

receiver manual for the individual channel level adjustment procedure. If your receiver

Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may

sound noisy or distorted, and the Auto On/Off feature may not operate properly.

(8) Optional Rack Mount Ears (Included)

These ears can be attached to the SC-602 amp to allow standard 19” rack mounting.

REAR PANEL CONNECTIONS

Following are brief descriptions described in Figure 2. More detail on these controls can be

found in the next section.

Figure 2: Rear Panel Connections of the SC-602 amplifier.

(9) Thru Jacks

These RCA connectors are for passing along the same signal that goes into your subwoofer

to a second “daisy-chained” system. The signal fr

om these RCA connectors is the same as

the input signal.

(10) Line Input / LFE Input

Connect these jacks to the LINE OUT pr

eamp output, LFE output, or subwoofer output jacks

of your receiver/processor. If using the LFE output from your receiver or processor, plug

the single cable into the jack labeled LFE input or, for more signal, use a “Y” connector

(optional) and feed the signal into both “R” and “L” inputs. Examples of these types of

connections can be found in Figures 2A and 2B.

11) IR Input

An IR repeater can be connected to this mini-jack.

(12) 12V Trigger

When this 2-conductor mini-jack is connected, the amplifier remains in power-off mode until

the trigger is applied. The correct trigger is +12V on the tip of the connector relative to the

grounded sleeve.

(13) RS-232 In

Use this port to communicate with an RS-232 controlled touch panel system. See Appendix

A for an explanation of the use of the serial port, available commands and their formats.

(14) Signal Sensing Auto On/Off Switch

With this switch in the “standby” position, your subwoofer can be safely left with the main

power switched on continuously. The subwoofer amplifier will turn itself on automatically when

an audio signal is present. If no signal is present for approximately 10 minutes, the unit will

switch to standby mode. While in standby mode, your subwoofer amplifier will draw very

minimal power. This function can be disabled by leaving the switch in the “always on” position.

(15) Speaker Level Input Terminals

If you do not connect the SC-602 amplifier to your receiver using the line input/LFE input

connection (Item 10) connect these input terminals to the speaker output terminals of your

amplifier or r

eceiver. If you use this method of connection, make sur

e to select the “lar

ge”

speaker option in the receiver’s speaker set-up menu. Also, select the option for no

subwoofer. This will make sure all bass and LFE information is fed to the speaker outputs and

be received by your SC-602 amplifier.

Note: Using both speaker terminals and the line level inputs is not recommended, as this may

damage the SC-602 amplifier or your r

eceiver

(16) Speaker Level Output T

minals

These connections send a crossed-over speaker-level signal to the front speakers. When

connected in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes

the task of reproducing frequencies below 80 Hz from your satellites, enabling them to do a

better job reproducing high frequencies.

You may also connect your satellites directly to your receiver or amplifier along with the

subwoofer if you wish to bypass this crossover.

An example of a speaker-level connection is shown in Figure 3.

www.velodyne.com

SC-602 Amplifier User’s Manual

Figure 3: Speaker-Level Connection.

(17) and (18) Subwoofer Connection 5-way Binding Post Terminals

Connect the output terminals to the subwoofer being controlled by the SC-602 amplifier. Only

connect ONE subwoofer to each red/black pair of subwoofer output ter

minals - DO NOT

connect multiple subwoofers to the terminals in any configuration.

Caution!!! To avoid damage to your SC-602 amp and subwoofer, be sure to maintain correct

polarity when making all speaker connections; red (positive) to red, and black (negative)

to black. Be sure that all connections are tight, and that there are no loose strands or

frayed wir

es.

(19) Power Cor

d Adapter

Connect the detachable power plug to this male inter

face connection. The detachable cord

allows for easy replacement should the original become damaged.

(20) Main Power Switch

Press the POWER switch to the ON position to activate the amplifier. If the unit is to be left

unused for an extended period of time, move this switch to the OFF position to prolong the

life of the amplifier

(21) Fuse

If the unit is not functioning, check the fuse. If the fuse is blown, replace with an identically

rated fuse. If the fuse blows again, r

efer the unit for service.

SC-602 Amplifier User’s Manual

he SC-602 amplifier is equipped with both speaker-level and line-level inputs. Use the

RCA/Phono type “INPUT” jacks when connecting from a pre-amp, signal processor, or line-level

crossover. The “SPEAKER LEVEL INPUT” jacks connect directly to the speaker outputs of an

integrated amplifier or receiver. Your amplifier section will notice no additional loading effects

when you use these inputs because of their high impedance.

Note: Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT”

connections simultaneously.

ABOUT LOW-PASS CROSSOVERS

All of the SC-602 amplifier inputs sum the left and right channels together and the resulting

signal is passed through an adjustable low-pass crossover before being amplified. The crossover

control allows you to adjust the upper limit of the subwoofer’s frequency response from 30 to

160 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control

to. The slope is 24 dB/octave.

You should set the crossover frequency to obtain a smooth and seamless transition from the

subwoofer to the main speakers in your system. If your main speakers are small with limited

low frequency output, you may wish to choose a higher frequency (such as 100 -120 Hz) than

you would with larger speakers which have greater low frequency output. The SC-602 amp’s

crossover has a default of 80 Hz.

Most r

eceivers and processors provide a menu option in which you can characterize main

speakers as “lar

ge” or “small” speakers. This affects the bass signals passed to the main

speakers. We recommend in most cases setting the main speakers to “small,” despite their

size and frequency response characteristics, allowing all multi-channel bass and LFE signals to

be passed to the SC-602. This is because the powerful 400 (x2) watt SC-602 amp combined

with the SC-600 subwoofer ar

e more likely suited to low bass reproduction than your amp and

main speakers. With the burden of low frequency reproduction relieved, your speakers will

exhibit better performance, and your overall system performance will improve.

Disabling the Low-Pass Crossover (Subwoofer Direct)

If your receiver/processors provides a crossed-over signal to the subwoofer you may want to

bypass the SC-602 amp’s low-pass crossover. To do this, depress both the Crossover UP and

Crossover DOWN buttons simultaneously. The numeric LED will show

indicating that the

low-pass crossover has been defeated. To reactivate the low-pass crossover, simply push the

ossover UP or Cr

ossover DOWN buttons.

A WORD ABOUT YOUR HOME THEATER RECEIVER’S

CROSSOVER AND THE SC-602 AMPLIFIER’S CROSSOVER

Your Velodyne SC-602 amplifier is designed to operate using the full range audio signal for

input when using the built-in crossover. Many home theater processors/receivers have a

“subwoofer out” jack that performs this same function and are designed to be used with

a powered subwoofer.

Rear Panel Connections — Detailed Explanation

www.velodyne.com

SC-602 Amplifier User’s Manual

n these installations, you may want to bypass the crossover in either the processor or the

Velodyne SC-602 amplifier as described above. However, in some cases you may want to use

OTH crossovers. If you choose to do this you should stagger the frequencies, (i.e., 120 Hz

subwoofer, 80 Hz processor) for best results.

Note: If not using an external crossover, you should use the subwoofer’s built-in crossover for

optimal performance. When using a single RCA sub out from the processor, it does not matter

which line level input (L/R) is used.

A WORD ABOUT INTERCONNECT CABLES

When connecting the Velodyne SC-602 amplifier to your subwoofer using the speaker level

connections, use a high quality speaker cable. It is recommended that you keep the length of

cable as short as possible to avoid any potential external interference problems.

When connecting the SC-602 amplifier to your subwoofer, use a quality speaker cable that is

at least 14-gauge. Be very careful to avoid any loose or frayed strands that could result in a

short, causing a dangerous condition and possible damage to your unit. Cables of extremely

large size are typically not required. Extremely large gauge wire may not properly fit in the

binding posts, resulting in a poor connection and possible short circuits.

A WORD ABOUT SUBWOOFER PLACEMENT

Subwoofers operate at extremely low frequencies, which are primarily omni-directional. Keep in

mind that fr

equency response and output level can be drastically influenced by r

oom placement,

depending on the acoustic properties of the listening room. Typically, the optimum

location for a subwoofer is in a front corner of your listening room where the greatest output

levels and optimum low frequency extension can be found. Typically, a minimum distance of one

to two feet from your TV to the subwoofer will be adequate to avoid any magnetic interference.

Remember that the built-in 5-band EQ will help to get the most performance out of your

subwoofer no matter where it is placed.

Caution!

This amplifier is an electronic device. Do not place the amplifier next to sources of heat such

as furnace registers, radiators, etc. Likewise, do not place the amplifier near sources of

excessive moisture such as evaporative coolers, humidifiers, etc. The power cord should be

routed in such a way that it will not be walked on, pinched or compressed in any way that could

result in damaging the insulation or wire.

www.velodyne.com

SC-602 Amplifier User’s Manual

our SC-602 amplifier can control the Velodyne SC-600 Series subwoofers as well as generic

passive subwoofers. Special internal software settings are designed to maximize performance

and reliability depending on the model of subwoofer being controlled, so it is important to match

the SC-602 amplifier with the subwoofer it is controlling. The SC-602 amplifier comes with a

default setting for the SC-600 IW subwoofer. When the unit is first powered up, the model

setting is displayed for two seconds on the numeric LED before the display reverts to the volume

setting. The subwoofer to be controlled is shown as follows:

Note: Both the IF and the IC settings apply to the SC-600 In-Floor/In-Ceiling (IF/IC) subwoofer

and have identical inter

nal settings.

To change the subwoofer to be controlled, first power down the amplifier using the main power

switch on the back panel (DO NOT use the power button on the front panel). Then, turn the

switch on while depr

essing any of the buttons on the front panel (crossover up or down, or

volume up or down). The unit will show the model it is currently controlling. To change the

model, simply push the crossover up or crossover down buttons and the model changes on the

LED display. Once the desired model is seen on the LED display, simply release the button. You

don’t need to do anything else - the model to be controlled is automatically stored in the

SC-600 amp’

s memor

y. To exit model selection mode, use the main power switch on the back

panel to power down and power up the unit. You should see the model you selected for two

seconds on the LED display before the display reverts to the volume.

Note: The SC-602 amplifier can easily control two subwoofers of the same type, i.e.,

two SC-600 IW or two SC-600 IF/IC subs. It is not intended to drive one of each

type simultaneously.

his section addresses EQ set-up and day-to-day usage of your SC-602 amplifier.

Remote Control

The features of the SC-602 remote control are listed below.

• POWER — This button forces your SC-602 amplifier unit into

standby mode. The power LED turns amber, the numeric LED

shuts off, and the amplifier puts out no power. The unit will

remain in this mode until the POWER button is pressed again.

To fully deactivate (i.e. power down) the unit, use the main

power switch on the back panel.

Note: The master power switch on the rear panel must be on

in order for the front power button to function.

• MUTE — This button mutes the subwoofer’s output. The LED

on the amplifier will show 00 if the unit is muted. To unmute

the subwoofer, press the MUTE button again and the original

volume setting shows on the LED.

• EQ — This button automatically equalizes the subwoofer’s frequency response using a 5-band

internal graphic equalizer. Prior to engaging this feature, hook up either one or two SC-600

subwoofers to the SC-602 amplifier

. To use this feature, first plug the supplied microphone

into the Mic-In jack on the fr

ont panel of the amplifier and place the mic in your preferred

listening position. Then press EQ on the remote for about 2-3 seconds. The subwoofer(s)

emits 12 “sweep tones” that cover the frequencies between 20 and 150 Hz. The LED

displays “AU” during the Auto-EQ process. After the sweeps are complete, the unit saves its

EQ settings and r

eturns to normal operation. To prevent accidental invocation of the EQ

feature, you must hold down the EQ button for 2-3 seconds before the EQ sweeps begin.

Note: Each time the EQ feature is utilized, the EQ settings for the SC-602 amplifier are reset.

If the microphone is not plugged in, the SC-602 amplifier will emit one or two sweep tones then

cease the EQ operation. In this case, the pr

evious EQ settings will be pr

eserved.

• PHASE — These buttons allow you to optimize the subwoofer performance for the location

and your listening position. Play some bass-heavy music. While listening, push one of the four

phase buttons, listen for a few moments, and then press the next phase button. In most

installations, one of the four button positions will offer an audibly better blend of subwoofer

and speakers. Selecting the cor

ect phase position is that easy

. The LED will show the phase

selected by showing “PH” followed by the phase number: 0, 90, 180 or 270.

•

LIGHT —

If you wish, you can deactivate the numeric LED on your SC-602 amplifier

. To

do this, press the LIGHT button on your remote. To reactivate the LED, press the LIGHT

button again.

• NIGHT — Night mode limits the maximum dynamic output of the subwoofer for late night

listening or to be more considerate of close neighbors. Press the night button to turn the

ight mode feature on or off. Activation of night mode causes “n” to appear briefly on

the display. When night mode is deactivated, the display shows “n off” and then returns to

ormal function.

• VOLUME CONTROL — This control allows you to balance the output from the subwoofer with

the output of the main speakers in your system. This control should be set to achieve similar

volume level of both the main speakers and subwoofer. When pressing volume up or down,

the volume level change is shown on the numeric LED on the front panel.

WARNING: Some manufacturers preset their receivers with the Sub-Out channel signal at a

minimum level. It is very important to verify that your receiver Sub-Out channel is set to the

same output level as your front right and left channels. Refer to your receiver manual for the

individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low,

the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the

Auto On/Off feature may not operate properly.

Note: The volume can also be adjusted via the volume buttons on the front panel of the

amplifier. These buttons have the same effect as pressing the up and down volume buttons on

your remote.

• PRESETS — There are four presets, consisting of Movies, R&B – Rock, Jazz – Classical, and

Games. As a preset is chosen, the preset is shown on the numeric LED as P1 for preset 1,

P2 for pr

eset 2, etc. The presets pr

ovide the following characteristics for bass r

eproduction:

Movies: Maximum output and impact for explosions and other

action adventure movie content.

R&B – Rock:

Provides the driving bass found in today’s rock music.

Jazz – Classical: The tightest, cleanest, lowest distortion bass. The flattest frequency

response of the four pr

esets.

Games: Maximum loudness available for the impact of video games.

Each preset has its own characteristics with respect to subsonic filter, volume differential and

a single contour equalizer in order to optimize the listening mode for the preset.

you have restored defaults. The unit’s volume is reset to level 30 on a scale of 1 to 80.

Do not use any harsh detergents or chemicals to clean the SC-602 chassis. Abrasives,

detergents, or cleaning solutions will damage the finish on the SC-602 chassis. We recommend

using a damp cloth to clean the front, back and sides. Do not allow any liquids to enter the

SC-602 chassis.

During normal conditions, the amplifier may be left on continuously without any problems. If you

plan to leave the unit unused for an extended period of time, we r

ecommend that you tur

n of

SC-602 Amplifier User’s Manual

efore seeking service for your amplifier or subwoofer, please re-check all systems. Following

is a simple troubleshooting guide to assist you.

1. Verify that the unit is plugged in and power outlet used is active.

2. Is the power switch on?

3. Is the unit receiving an input signal from your receiver or processor?

4. Have all controls on the amplifier (volume, crossover, phase, etc.) been properly set?

5. If the unit has been running at high levels, one of the protection circuits may be engaged.

Has the amplifier overheated?

6. Has the power button been depressed on the remote?

7. Is the remote non-responsive? We recommend replacing the batteries in the remote.

If the protection circuitry is active, the unit may cycle on and off until operating parameters

return to normal. Under more serious conditions, the unit may shut off completely. Normal

operation should return upon cooling, but you may be required to turn the power off and then

on again to reset the unit.

The following conditions require service by a qualified technician:

1. The power cord has become damaged

2. The unit does not appear to operate normally or exhibits a marked

change in performance

3. The unit has been exposed to water

4. Some par

t of the chassis or circuitry is physically damaged
